Our Verdict

Dell S2721DGF

Dell Alienware AW2721D

The Dell Alienware AW2721D and the Dell S2721DGF are both great gaming monitors with similar performance. That said, the AW2721D has a higher max refresh rate and slightly better picture quality overall. They have similar response times, although the S2721DGF experiences less overshoot. The S2721DGF has much better reflection handling and better ergonomics, but the AW2721D feels better built, gets significantly brighter in SDR and HDR, and has much better accuracy out-of-the-box, although this can vary between units. The S2721DGF may represent a better value to some people.
